Posting Clinical Data

Creating or updating subject data in Rave is managed via the post_data method to RWS.


Authorization is required for this method.

Returns a rwsobjects.RWSPostResponse object which has attributes that report on the changes made and new counts of subjects in the study. On failure, raises an exception with a RWSPostErrorResponse attached in the error attribute that reports on the full source of the error as reported by RWS.

Option Description
headers={‘Content-type’: “text/xml”} Set custom headers. May need to provide a Content-type if your RWS version is set to accept different standard content-type than default.

Note that the content-type header that RWS will accept can be varied by configuration. The standard, default setting is text/xml. You should not need to specify content_type in the normal case.

Using Builders

Creating ODM strings can be error prone, especially when dealing with XML entities such as &gt; &lt; &amp; etc. rwslib provides the builders module to help build ODM documents using python syntax.

The ODM from the example above could be generated using the builder vocabulary:

>>> from import *
>>> odm = ODM("test system")(
...   ClinicalData("Mediflex","DEV")(
...      SubjectData("MDSOL","New Subject", "Insert")(
...         StudyEventData("Subject")(
...            FormData("EN", transaction_type="Update")(
...               ItemGroupData()(
...                  ItemData("SUBJINIT","AAA"),
...                  ItemData("SUBJID",001)
...               )
...            )
...         )
...      )
...   )
... )
>>> str(odm) #Returns the string representation of the odm object and all it's children.

See Using Builders for examples of using rwslib builder objects to create ODM messages.
